How to create file folder in runtime?

I was wondering how to create a folder name call "maths" in c drive in vb runtime.
and can anyone show me the simplest code.

Use the Dir function and MkDir statement to find if a folder exists and create one if it doesn't.

Code:

---

If Dir("C:\maths", vbDirectory) = "" Then
    MkDir "C:\maths"
Else
    Exit Sub
End If

I am appreciate it,
Thanks,Matthew Gates .
